TECWERK End Mill Ø20 mm — DIN 6527 L, solid carbide, TiAlN-coated, long

The TECWERK End Mill Ø20 mm is a long, four-flute solid-carbide cutter for universal roughing and general-purpose milling in steel and non-ferrous materials, featuring a TiAlN coating and a 45° helix for fast material removal.

• Solid carbide fine-grain body
• TiAlN coating for extended tool life
• 45° helix for high cutting performance
• Four flutes with roughing profile
• Cylindrical shank to DIN 6535 HB

High-precision engineering for dependable productivity

The long solid-carbide construction delivers a consistent cutting geometry and thermal stability even under sustained loads. The solid carbide fine-grain substrate ensures resistance to chipping and wear, while the TiAlN coating provides heat resistance and improved surface hardness; together these features lengthen tool life and reduce downtime. This combination supports high-feed operations and contributes to a predictable production flow in series machining.

Material versatility with clear performance advantages

Designed for demanding alloys, the cutter achieves very good results in steel, cast iron and non-ferrous metals, and is conditionally suitable for certain special alloys and stainless steel. The positive rake angle increases cutting efficiency and reduces cutting forces, which makes the tool particularly effective when paired with stable clamping and appropriate feeds. The result is efficient chip evacuation and fewer rework passes for many workshop applications.

Geometry tuned to reduce vibration and increase application flexibility

A special roughing profile on the cutting edges enables chip segmentation and lowers cutting vibrations, improving process stability during interrupted cuts. The 45° helix and four-flute layout balance axial and radial forces to maintain surface finish while enabling higher material removal rates. The inclusion of a neck relief (relief ground neck) and a 45° protective chamfer on the cutting edge improves entry behaviour and protects the tool during plunge and ramping operations.

Practical design and industrial compatibility for workshop use

The cutter has a cylindrical shank to DIN 6535 HB with h6 shank tolerance, enabling secure clamping in standard toolholders and reducing run-out. With a 50 mm length of cut and long overall length, the tool is suited to deeper slotting and extended reach operations where rigid set-ups are available. The right-hand cutting direction and the four-flute configuration make the tool a reliable choice for roughing passes prior to finishing with a dedicated finishing cutter.
